Hello freesurfers,

Suppose I do the following

mris_preproc --fsgd gender_age.fsgd \
  --cache-in thickness.fwhm10.fsaverage \
  --target fsaverage --hemi lh \
  --out lh.gender_age.thickness.10.mgh

Then open the output file lh.gender_age.thickness.10.mgh in mathlab using

result=MRIread('/path/rh.meditation.thickness.10.mgh');

Is it true that the actually thickness data is stored in result.volsize?

Suppose that I have 27 subjects, is there a way to assign these numbers to their corresponding subjects?

Thank you very much!

Sincerely,
